Watch! The Cabin in the Woods Trailer, Starring Jesse Williams

Joss Whedon is a big name in the geek world. He's the beloved creator of cult TV hits like Buffy the Vampire Slayer and Firefly, and he's directing the much-anticipated Avengers movie. And now he has another film hitting theaters — and it features a very familiar Grey's Anatomyface.

While Avengers is the big-name Joss flick coming up, devoted fans have been looking forward to his smaller-budget horror film, Cabin in the Woods, for a long time. The film's release has been delayed over and over again, but now the trailer is finally here — and it features Jesse Williams (Jackson Avery)!

That's right, Jesse plays Holden McCrea, one of the college kids who gets stuck in a very creepy cabin. Jesse joins Thor star Chris Hemsworth and Joss Whedon regulars Amy Acker, Fran Kranz, Tom Lenk in what looks to be a chill-a-minute story.
